Self-regulation theory suggests that lifestyle behaviors, such as diet, exercise, and medication adherence, are regulated by an individual's perceptions, beliefs, and attitudes. The theory postulates that individuals are motivated to regulate their health behaviors based on their personal goals, values, and beliefs. It further suggests that health behaviors can be modified by changing an individual's self-regulation processes, such as self-efficacy beliefs, goal setting, and planning. Self-regulation theory is based on the idea that individuals can be empowered to take control of their health by understanding and changing their behavior through self-monitoring, goal setting, and problem solving. Ultimately, the goal of self-regulation theory is to help individuals become more self-aware and actively engaged in managing their health behaviors, leading to improved health outcomes.
